Like all Of D3’s
performance and exterior upgrades, the performance packages offered
for the Cadillac STS and STS-V blend perfectly with the car, adding
performance and handling that is exhilarating while retaining the
car’s reliability and every day drivability. To prove this, a D3
enhanced 2007 STS-V was recently driven in hot LA traffic to a track
for some performance tests in less than ideal conditions. In spite
of temperatures in the 90’s, the car never missed a beat as it
recorded 0-60 times of 4.4 seconds and ran the quarter mile in 12.5
seconds at 112 MPH. After a day of testing the car was then driven
back through even hotter and more congested traffic without a
complaint.

The car that ran these
tests contained D3 Cadillac’s “Stage 2” engine power package. This
package boosts HP to 570+ HP (the test car had 575 HP) and torque to
500+. The Stage 2 engine power package includes upgraded Spark
Plugs, Boost Pulley Upgrade, Intercooler Upgrade, and new ECU tune.
This package requires a PCM reflash to maximize tune and engine
potential. Not only does it increase engine performance, it also
focus on increasing engine efficiency, both thermal and fuel. The
results are constant repeatable performance that will not fade like
common supercharged vehicles.
The Stage 2 engine power package is one of four different power
package offered by D3, each providing more performance. The ultimate
package is the Stage 3 which is customized to the owner’s tastes and
yields in excess of 600 HP. Also offered are individual component
upgrades to the air intake system, the intercooler, the spark plugs,
the ECU system, the exhaust system, the supercharger, and more.

To provide braking and
handling that match the car’s enhanced power, D3 provides many
options. These include:

• Suspension
lowering for improved cornering and a great “look”.
• Several brake system upgrades including complete packages as
well as component upgrades to rotors, pads, and brake lines.
• Several wheel and tire options to maximize performance and
look.

The car in the recent
test had D3’s “Big Brake” upgrade package which includes 8-piston
front calipers, 4-piston rear calipers, and 15” high performance
drilled/slotted rotors. Wheels are Forgeline 3-piece performance 20”
with Proxy Toyo Tires. For a complete list of all upgrades, go to
